The Fit2 Air offers the same convenience and ease-of-use features as our #1-rated KeyFit 30 Infant Car Seat, plus the added benefit of extended rear-facing use up to at least 2 years of age. Two unique stages allow parents and caregivers to take advantage of the portable infant carrier and stroller compatibility for an additional year. Stage 1 offers more reclined seating and removable head & body support for newborns and smaller infants. In one simple motion, the stay-in-car base transitions from infant position to toddler position, offering more upright seating and extended legroom for toddlers 9-24 months old. The 7-position headrest adjusts easily with the 5-point harness to provide protection as your little one grows. The adjustable carry handle lowers with one hand for easy access while loading and unloading. Next Level Comfort The Fit2 Air takes comfort to the next level with 3D AirMesh channels for breathability and a full-coverage, ventilated canopy for increased airflow. The dual-density, cushioned seat pad features luxuriously soft, premium Italian fabric that resists pilling and everyday wear and tear. The seat pad is removable and machine washable to keep it looking like new. Easiest to Install The Fit2 Air is designed with smart functionality that makes it the easiest to install simply, accurately and securely. ReclineSure spring-loaded leveling foot works in tandem with RideRight bubble levels to easily verify and achieve proper base angle during installation. Premium LATCH connectors and a force-multiplying SuperCinch tightener help achieve a secure fit with a fraction of the effort. The base is also designed with easy belt routing and integrated lock-offs for alternate installation with the vehicle seat belt. Premium Protection The carrier shell is lined with high quality EPS energy-absorbing foam for improved side impact protection. An integrated anti-rebound bar increases surface contact between the base and vehicle seat for added stability and leverage and a more secure install.
